It's just two different versions... EX has black hair and pistol and Regular has Red hair and Rifle, both versions come with the orange blade.
Both her hands slide out and you can put in the hand with the pistol on one side and the hand with the rifle in the other.
Would of been cool if the EX came with both pistol and rifle..
I ordered mine from Bioware direct and they sent me the Regular one by accident, so I told them and they were going to replace it with an EX but I decided just to keep the regular one and order a EX again.. Cool thing was when I got my receipt for the EX they knocked $13 off for messing up on my first order, so I got the EX at a discount
